Be it known that l, SAMUEL G; Roslsoisr, of Lexington, in the county of Fayette and Stateof Kentucky, have invented certain new i and useful Improvements in emp-Brakes and l'hereby declare that thefollowing is a full, clear, and exact description thereof, refin s, which form part of this specification.

erence being had to the accompanying drawhis invention is an improved machine for r'ealring and cleaning fibrous plants,

- such as hem sisal flax, &c.' and its object is! to mechanically separate thefibers from the Woody matters or shreds in a thorough man-E ner and at the same time keep the fibers in? cod-condition and free or practically free; om snarls and tangles, which wouldrender;

' them useless for subse uent manufacture o r re g w customarily employed.

To these ends the invention is desighed or which they are keep the fibers continually moving-endwise.

through the machine and to sub'ect them to such repeated workings that t ey' will be freed from the woody useless and injurious portions oi the plant and will be rendered :flexible and pliableand clean; and the invention consists in the novel construction and combinations of mechanisms-for accomplishing the desired ob ects, as hereinaiter"d'escribed and claims and in the accompany ing drawhigs I have illustrated amachine I .which embodies the invention the best form not; known to me but as it iscapable of modification withinthe sco e of the in.-

vention I do not restrict myse i" to the par ticulariorm and arrangement of parts-shown in thedrawings.

In said drawings, Figure 1 is aside elevation of the complete machine, Fig. 2 is a side elevation of'the opposite side oi the machine. Fig. 3 is a detail plan view of-the "drivingmechanism shown m Fig. 2, Fig. 4

is an enlarged longitudinal section through the main portions of the machine. I

In the drawings, 1 1 designate breakingrolls, '(preferablylrmgitudinally cdrrugated or as shown, and journaled in suitable the shafts of the rolls and gears 1 1 being journaled on studs fixedto the main frame.

One of said rolls, preferably the upper, may

be journaled in yielding bearings pressed to- Ward the other roller by stout springs 1, ad

- the shaft of roll 1, meshing with a pinion 3 on the' main shaft 3, which is journaled in suitable hearings on the frame, located at the inner side of'rolls-l l 1 Alter passing the breaking-rolls'l- ,1 the broken stalks are fed between crushing-rolls 2 2', journaled in suitable hearings on the main frame at theinner side of the breakingrolls, the upper one of the crushing-rolls'being preferably journaled in yieldable bearings and forced toward the other roll by means of springs 2 adjustable-by nuts and bolts 2 as shown. The crushing rolls may be driven at proper speed in opposite directions by means of a train of gears 2 2 2 2*, the gears .22 Z being fast on the shafts of rolls 2 2? and the intermediates 2 2 being journaled on studs attached to the main frame. Gear 2 also meshes with gear 1 on roll 1 and is driven from and by the latter. After passing crushin -rollsi2 2 by which-the shreds previously roken by the breaking-rolls are crushedand disengaged from the fibers, the fibers and stalks pass over a breaker-bar 3 on'which they are broken by the action'of. ribs 3 on a beater-cylinder 3, which is mounted upon and rotated. with the maiii shaft 3 and rotates in a direction-toward. the

break-bar, so as'to beat down the fibers! assing thereover. This beater separates a arge portion of the shreds from the fibers, and its action is supplemented by a secondary beater 3, locatedbelow-the breaker-bar and mount ed on a shaft 3', which is rotated in a direction contrary to shaft 3 by suitable gearing or. as

"shown, by means of a belt 3 running overa pulley 3 on. shaft 3 andunder a pulley 3 on shaft 3 to a fan-pulley hereinafter referred to. The heaters 3 3 are preferably provided on their peripheries with longitudinal bars 3,

triangular incl nes-section and adapted to strikeithefibrous stalks rapidly and alternately'aft'er they leave the breaker bar and .l mock the shreds out'of the fibers, comb the ,llbersout straight, and work them into'a pliloo n'ises a lar e cvlinder 4 )rovided with lon ih l P tudinally-disposed bars 4", approximately triangular in rrossscct1on a coaetmg endless rubber or cleaner-6, havmg a series of transverscly-arranged triangular bars 5",

adapted to coact with bars at on cylinder 4, and an endless fiber-carrier 6, ru1"ning around cylinder r and between it and the rubbing device 5 and adapted to remove the cl aned fibers from the cylinder 4 in a smooth and orderlycondition.

The cylinder 4 is mounted on a shaft 4", journaled in suitable hearings on the main frame and driven by suitable means in a direction opposite to the-rotation of heater 3. As shown, shaft 4" carries a sprocket t". driven by a sproclu-t-cluiin at" from a sprocket 1" on the shaft of roll 1.

The endless cleaner or rubber 5 runs over pulleys 5" 5*, mounted on transverse shafts 5 5". journaled on the main frame adjacent cylinder 'l so that the bars 5 on the lower run of the endless rubber will alternate with and engage between the bars 4" on cylinder 4, by-which motion will be imparted to the endless cleaner, and the fibers caught between the bars 4" and 5 will be rubbed and worked up by the rubbing and rocking action of the bars 5 against and between the bars 4.

The f? ercarrier 6 comprises endless side chains r :nning over cylinder a and pulleys 6" on a sha ti", 0 )urnaled in the mainframe in rear of ey uder 4, the side chains being connected by rods 6' at regular intervals. which mg between the bars 4" 5" pass over rods 6" vided with longitudinal bars and will be removed from the cylinder t by the upper run of ca rrier 6, as is obvious, and

taken thereby to and over the pulleys 6 where they are discharged onto a final beater 7, over which they pass to delivery-carriers h and 9, as shown.

The beater 7 is preferably a cylinder pro- 7, preferably triangular in cross-section,and is mounted on a shaft 7", which is driven by a crossed belt 7 from a pulley 3 m on shaft 3. The delivery-carriers 8 and 9 preferably are construeted substantially like carrier 6that is, of side chains connected by rods 8% 9. The carrier 8 runs ove sprockets 8" 8, mounted on shafts arranged transversely of the main frame, as shown. The carrier 9 runs over sprockets 9" t)" t)", mounted on shafts 'suitably supported on the main frame, carrier 9 having a triangular run, a short downwardlyinclined portion between sprimkots 9" 9",

l 8 and 9.

which is adapted to direct the tiber discharged by carrier 6 onto the beater 7, and an upwardly-inclincd run between sprockets t)" 0, parallel with the upper run of carrier 8, sothatthe'tibcrs will be carried away from beater 7 between the parallel IIIHS of carriers The carriers b and t) can be driven by a belt 4", running over a pulley 4 on shaft e, the said belt running under a pulley a on the shaft carrying sprockets t)" to and over a pulleyS on the shaft carrying sprockets S and back to pulley 4", as shown. In this manner both sets of carriers 8 and 9 are moved in the right direction.

In order tf) direct the fibers across the space between the heater 3 and the rubbing and cleaning devices, l preferably em )loy an air-blast, which is derived from a fan located in a casing 10 beneath the main frame and having a pulley it)" on its fan-shaft, which is driven by belt 3 from the pulley 3 the re turn run of the belt passing underan idler 38 as shown. The air is conducted from the fan-casing through a trunk 1t) to a head 10, located below and adjacent to the first heater in such position as to drive the loose par tlycleaned fibers upward to and between the meeting-points of the cleaner-belt 5 and cleanlug-cylinder 4. The shreds separated from the fibers by the beaters 3i 3" can be dropped into a box or receptacle 10", which is connected by a trunk 1t) with the casing of fan 13, and the shreds can be blown from re.- ceptacle It)" through trunk It)" to fan 13 by means of air-jets supplied from the pipts l0 through pipes 10 or otlu-r-suitable manner. Any other suitable means for removing the shreds can be employed.

The fan 13 may be one of the ordinary pneumatic blower-fans such as used in menmatie stackers and is adapted to discharge the shreds and matters separated from the tibers and dro ped into its casing through a pipe 13, which can be extended :to any suitable dischurging-point. The fan 13 can be operated in any desired manner, and it is indicated in Fig. l as operated by means of belt 13* and pulley 13 from a pulley on the shaft 7" The endless-belt rubbing devic i 5 can have its tension adjusted by mounting one of its supporting-shafts 5" in adjustable bearings which are held outward so as to tension the belt by means of springs 12 on rods 12, at tached to the bearings, and whose tension is regul'able by nuts 12".

The stalks are fed into the machine betweenthe breaking-rolls 1 I froth a platform 11', mounted on the machine at convenient point in advance of said lneakingrolls.

Operation: The stalks of fibrous material are fed in endwise between rolls 1 and 1, by whieh they are broken or cracked into short. lengths. Then the cracked stalks-pass be.- tween the crushing-rolls which crush ssaaos the woody matters in the broken stalks and loosen them from the fibers. The stalks then pass on over breaker-bar 8 and are struck bythe bars 3 on the first beater 3 the tendency of which is to drive the stalks down and to knock the shreds out of the fibers. The descending fibers are struck up wardly by the bars on the oppositely-rotating beater 3" and pushed outward over the jet-head 10, by which they are blown upward againstthe beater 3 again, so that the fibers are further beaten and combed by bars 3, and by the combined action of the said beater and air-blast the fibers are directed to and between the endless rubbing device 5 and the separating-drum 4, and the fibers are caught and held between the bars a and 5,

' and as these bars travel together the rubbingand scrubbing action on the fibers tends to thoroughly separate them from any'woody matters still ad ering thereto. After pass- .ing through the rubbing devices the fibers are carried over by the endless carrier 6 to the delivery-carriers 8 and 9; but before reaching the latter they are whipped out by the final beater 7, which produces thefinal separation of the fibers from the shileds and,

small Woody matters, and the clean fibers are delivered by the chains 8 and 9.1 I

The main frame may be mounted on wheels, if desired, so as to be transportable from place to place, axle bolsters being indicated at 16 16 in Fig. 1.
